Waltham Forest and Newham are among the five boroughs within the proposed Olympic Games site. If, on 6 July, the International Olympic Committee (IOC) selects London to host the 2012 games, the council would be charged with communicating a vast regeneration programme.
The IOC evaluation commission praised London and Paris for their 'very high- quality bids' in a crucial report published this week.
As well as the Olympic Games' investment in the borough's infrastructure, and its potential to create jobs in the east London region, the 'velodrome' will be built regardless of whether London gets the go-ahead. There are also plans to regenerate the town centres of Leyton and Leytonstone in the borough .
The last Audit Commission inspection in December rated the council 'weak', but previously it was rated 'poor', the lowest mark.
'The council wants to become "excellent" so there will be a lot of internal comms work for Nick,' said Waltham Forest press and PR manager Melissa Hoskins.
Williams will be charged with corporate marketing, press, internal comms, e-comms, design and a residents' publication. He takes over from Seth Brook, who leaves on 22 July to go freelance. Brook has spent three years at the council where he leads a team of 17.
